To all whom it may concern Be it known that 1, CHARLES C. SUNDER LAND, a citizen of the United States, residing at Trenton, county of Mercer, and State of New Jerse have invented certain new and useful Slings and the like, "fully described and represented in the following specification and the accompanying drawings, forming a part of the same. I

This invention relates particularly to wire rope slings of that'classhaving two wire rope loops combined to form a bridle sling, the especial object of the invention being to provide a construction in which the two loops shall be combined by" a thimble into a single eye to receive the hoisting hook, thus avoiding the use of any -hook, gromet,

claims.

- lln the drawings,.Figure 1 is a side view ofthe bridle sling, with the double rope thimblc. Fig. 2 is an enlarged view of the thimble portion of Fig. 1, with the thimble partly in section and one of the ropes broken away to show the construction. Fig. 8 is an edge view of Fig. 2. Figs. 4, 5 and 6 are sections on the lines 1-4, 5-5, and 6-6 of Fig. 2. Fig. 7 is a detail section correspondiii) ing to the upper part of Fig. l, showing a. modification of the thimble with the ropes omitted. Fig. 8 is a section corresponding to Fig. 6, but showing the thirnble 0 Fig. 7.

Referring to the drawings, the bridle sling is shown as similar to that of United States Letters Patent to lituland, No. 1,063,738, dated June 3, 1913, A, A being the two loops or slings of the bridle, with the running gromets B thereon. The. two slings or loops A, A, however, instead of having separate thimbles forming separate eyes at the load end, as shown in the Ruland patent,

have one thimble C forming a single eye of the two loops or slings, which eye receives the hoisting hook D. The thimble may be of any suitable general construction, so formed as to provide grooves for the ropes Specification of LettersJPateut.

improvements in Wire-Rope of'the two loops or slings d, A, and these grooves may be entirely or partially separated or run together without any intervenmg wall to separate the ropes, within the ber 15th, 1914, to which reference may be' had for a full description of its detail construction, 10, 11 bein two sections or sides of the thunble C, divided substantially central of the rope grooves and secured to gether b rivets 12, the inner end of the thimble having the overlapping ribs 13' between the ends of the rope grooves and the overlapping rlbs '14 outside the-rope grooves and by whlch the ropes are held in place, and

these overlapping ribs being secured together by pins 15, and the usual overlapping ears 16 at the outer end of the thimble be ing shown, for holding the ropes in place. The thimble differs from that of said Letters Patent No. 1,121,306, in that it is formed to provide a plurality of grooves 01, a for the two ropes of the loops or slings A, A, these grooves being shown as formed in the separate sections 10, 11, and, in the construction shown in Figs. 1 to 6, as partially separated by a rib formed on the thimble and projecting between the ropes. This separation of the ropes will usually be found preferable but may be omitted, as shown in Figs. 7 and 8, in which the rib b is omitted, no provision being made for separating-the ropes in the grooves a, a. The thimble, also, is preferably provided with the curved bearing surfaces 17, 18, extending somewhat along the ropes from the thimble proper and curved edgewise and sidewise of the thimble, so as to permit the wide separation of the two parts of each loop, and the-spreading apart of the two' loops without the wear which would result from bearing on the straight inner ends of the thimble.

It will be seen that by my invention the two loops or slings A, A are combined into a single hook eye, thus avoiding the use of any book, gromet, ring, or other device for connecting the two eyes of the loops, and
